APPARATUS FOR TEEATI NG PAPER.

Specification of Letters Patent.

Patented Dec. 12, an.

Application filed tictober 12, 1915. Serial No. 55,550.

citizen of the United States, residing at Appleton, in the county ofOutagamie and State of Wisconsin, have invented new and usefulImprovements in Apparatus for Treating Paper, of whichthe following is aspecification.

The present invention pertains to a method and apparatus for treatingpaper, and more especially of paper in the form of continuous strips orwebs, and comprehends improvements over the method and apparatus fortreatin paper as disclosed in my prior Patents Nos. 1,117,113 and1,117,114.

The objects aimed at by the present invention are to reduce the size ofthemachine, and decrease the number of its parts, with a resultantdecrease in the cost of construction of the machine; and to provide anapparatus or machine which will require less floor space and care, andwhich will produce a Wet web of paper free of spots and specks of dirtwhich have heretofore been occasioned on the wet web due to the latterpassing through an extended machine and over a. substantially drywinding drum upon which dirt accumulates and peels ofi' and sticks tothe wet Web before the latter is wound into a roll.

lit is also an object of this invention to produce an apparatus ormachine as above described that will prevent air blisters and wrinklesupon the web of paper under treatment.

With the above ends in view, the invention contemplates a sizing tankover which are mounted the superposed expressing roll ers and anadjustable support for the reel on which the web is Wound up, thesurface with the the movement of which latter efl'ects the winding ofsaid web upon the reel.

l lit is alsoa feature of the invention to pro-. vide a pair of spacedrollers mounted directly over the upper expressing roller for guidingthe web from the latter to the reel,

and to also provide a spreader roll disposed between said guide rollers.

With the above ends in view, the invention consists in a certain novelconstruction, combination and arrangement of parts hereinafter morefully described and finally pointed out in the appended claims.

In the drawings which form part of the specification: Figure 1 is a sidesectional view of the apparatus contemplated by the invention; and Fig.2 is a top plan view of said apparatus.

The new and improved treatment, like the earlier treatmentsabove-mentioned, may be carried out with or by the aid of any suitableapparatus, an embodiment of that preferred being, shown in theaccompanying drawings.

In the drawings, 1 indicates the strip or Web of paper undergoingtreatment and 2 the bath of gelatin or other sizing medium through whichthe same is passed by immersion as the initial step of such treatment.This Web of paper may or may not have been subjected to the usualpreliminary engine sizing, with or without mordants, and may be led tothe bath for immersion directly from the machine, or after it has firstbeen reeled up in a dry state. On leaving the size bath, the immersedwet paper web passes between the rolls 3 and 4: which serve to removeand express the excess size from the web, and from these rolls it iswound, while still in a wet'state, directly upon the Winding reel 5 ablearms 6, as clearly shown in Fig. 1 of the drawings. The adjustable arms6 have one end pivotally secured to the axis of the roll 4, as shown at7, and are held in an inclined position by the connected links 8 and 9which are adjusted by the mechanism 10. The a'rms 6 and their supportingand adjusting mechanism are preferably of the type shown and describedin the aforesaid patents and are designed for supporting the reel ofpaper in frictional contact with the winding drum. In the presentinstance, the arms 6 are adapted to adjustably support the reel 5 andpermit the same to gravitate in frictional contact with the peripheralsurface of the roll 4 at a point above the axis thereof. It will thus beseen that the roll 4- performs a dual function. that is, by

supported upon the adjustthe invention to pass the web over a spreaderroll. after the web has passed through the size expressing rolls andbefore the same is wound uponfthe reel 5. For carrying out this purpose,it is preferred to pass the Web over spaced guide rolls 11 and 12immediately before the same is wound upon the reel. Interposed betweensaid guide rolls is the spreader roll 13 yieldably mounted so as to besensitive to the varying thicknesses of the sized web.

With the method and apparatus above set forth, it will be obvious thatthe sized web will be produced free from spots and specks of dirt whichoccur on the web when the same is passed through an extended machine andwhen the reel is wound from a substantially dry winding drum, since thesize from the web accumulates on the surface of the drum, hardens',peels off, and is finally deposited upon the web, causing considerablewaste of the latter. In the present instance, the reel is wound directlyfrom one of the sizing rolls itself, which latter is constantly wet withthe excess sizing being squeezed from the web which consequentlyeliminates-the possibility of such hardened extraneous substances,formed on the surface of the drum, being deposited on the web as thesame is being wound, as is the case with the dry winding drums now inuse. Also, in view. of the simplified construction of the apparatus, theweb does not pass over or between a multiplicity of rolls and otherelements, so that it is not exposed to the foreign substances in theatmosphere which are frequently deposited thereupon.

According to the construction shown in the drawings, the rolls 4 and 5are superposed and rotatably mounted in the uprights- 14 secured onopposite sides of the tank 2, the lower roll 3 beingof less diameterthan the upper roll 4. The upper ends of the uprights 14 are providedwith the substantially horizontal extensions 15 which are slightlyinclined, as shown in Fig. 1. The extensions 15 extend'from saiduprights in a direction away from the reel 5 and have journaled at theiroppositeends the guide rollers 11 and 12, respectively, which extendtransversely of thetank 2 and are parallel with the rollers 3 and 1 andthe reel 5.

18' is secured on extensions 17 projecting from the uprights 14 andengages with the roller 4 under the reel 5 for cleaning the surface ofsaid roller.

From the foregoing, it is believed that a clear understanding of thepresent invention may be had. However, it is to be understood thatcertain changes as to the precise construction, combination andarrangement of parts may be resorted to that fall within the legitimatescope of the appended claims.

What is claimed is:

1. An apparatus for treating paper web, comprising, a size bath throughwhich said web is passed, size-expressing rolls disposed over said bathand between which said web is passed and fed forward, and a reel onwhich the web is wound up, said reel supported to hold the web thereonin frictional contact with one of said rolls so as to cause the rotationof said reel therefrom.

2. An apparatus for treating paper web, comprising, a size bath throughwhich said web is passed, size-expressing rolls disposed over said bathand between which said web is passed and fed forward, a winding reel forthe web, and an adjustable support whereon said reel is carried to begravitally held in frictional contact with one of the said rolls wherebysaid web is wound and the reel operated from said roll.

3. An apparatus for treating paper web, comprising, a size bath,size-expressing rolls disposed over the bath and feeding said webforward, a winding reel for the web in frictional contact with one oftherolls and to be operated thereby, and a spreader roller over whichsaid web is passed after the size has been expressed therefrom andbefore being woundupon said reel.

4. An apparatus for treating paper web, comprising, a size bath,size-expressing rolls disposed over the bath and feeding said webforward, a winding reel for the web and in frictional contact with oneof the rolls to be operated thereby, spaced guide rolls, and a yieldingspreader roller disposed between said guide rolls, said web being passedover said guide rolls and spreader roller after the size has beenexpressed therefrom and. before being'wound upon said reel.

Intestimony whereof I have hereunto set my hand in presence ofsubscribing witnesses.
